THE SKELETON IN THE FLYING LEMURS. 



205 



the skins and ostcological material ol" the Philippine forms were as yet 

 not sufficiently extensive in the National Mnseum collections to ditfev- 

 entiate them. In addition to the aloove-mentioned material, Mr. Miller 

 placed at my disposal a particularly fine and perfect mounted skeleton 

 of an unidentified Malayan form of flying lemur belonging to the 

 National Museum. This specimen was photographed for me by Profes- 

 sor T. W. Smillie, chief of the photographic division of the National 

 Museum, and the reproduction of this photograph illustrates the present 

 memoir as a frontispiece. It is particularly valuable as showing the 

 skeleton in one of these animals with all the bones, even including the 

 hyoid and trachea, normally articulated. There is listed in the following 

 tables all of the osteological material (October 1, 1910) representing 

 the flying lemurs in the collection of the United States National Museum, 

 which I have compared and studied. The scientific name given is the 

 name on the label attached to the' specimen. Such information likewise 

 applies to the locality, sex, and name of collector given. In some in- 

 stances the condition of the specimen is added.
